Qualcomm Snapdragon 626 vs Qualcomm Snapdragon 660 vs Qualcomm Snapdragon 410 MSM8916

Qualcomm Snapdragon 626

The Qualcomm Snapdragon 626 (SD626) is a mid-range octa-core SoC with eight ARM Cortex-A53 cpu cores at up to 2.2 GHz, an Adreno 506 GPU, a DDR3L-1866 memory controller and a X9 LTE (Cat 7, 4G+, 300 Mbps down, 150 Mbps up) modem. Furthermore, the chip supports 802.11ac WiFi and Bluetooth 4.1. It is manufactured in 14nm FinFet. The processor performance should be a bit higher than the average Snapdragon 625, due to the 200 MHz higher maximum clock speed.

Qualcomm Snapdragon 660

The Qualcomm Snapdragon 660 (SD660) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. Announced in mid 2017, the SD660 is the successor to the Snapdragon 625. It features 8 Kryo 260 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of four cores with up to 2.2 GHz and a power saving efficiency cluster with up to 1.8 GHz. Both clusters can also used together.

In addition to the 8 CPU cores, the SoC integrates a mid range Adreno 512 GPU with a LPDDR4 memory controller (dual-channel 1866 MHz)  and supports Wi-Fi (802.11ac + MIMO, max. 867 Mbps), Bluetooth 5, and LTE (X12 LTE modem with up to 600 Mbps download and 150 Mbps upload).

Performance

In Benchmarks of the Oppo R11, the CPU part of the Snapdragon SD660 performs between former high end Socs like the Snapdragon 821 in the Pixel XL and the Snapdragon 835. The graphics performance is however much lower, as the Adreno 512 is only a slight upgrade of the older Adreno 510 (due to the higher clock speed).

CPU

The Snapdragon 660 is based on a similar concept as ARM's big.LITTLE, which combines a low power CPU cluster (2x Kyro clocked at up to 1.8 GHz) and a performance CPU cluster (2x Kyro clocked at up to 2.2 GHz). The clock speed of each cluster can be individually adjusted (but not per core) and the lowest clock speed is 310 MHz (unverified).

Power Consumption

Thanks to the new 14 nm process, the energy efficiency has been improved noticeably compared to its 20 nm predecessors.

Qualcomm Snapdragon 410 MSM8916

The Qualcomm Snapdragon 410 (MSM8916) is a ARM based mid-range SoC for tablets and smartphones (mostly Android based). It was announced in Dec. 2013 and was the first 64-Bit SoC by Qualcomm. It integrates four ARM Cortex-A53 (quad-core) processor cores, a Adreno 306 graphics card, a 64 Bit LPDDR2/3 memory controller and WLAN, Bluetooth, and UMTS/LTE radio.
